1 Claim. (Cl. 24-73) More particularly, this invention is directed to improve the method of fastening molding, trim strips and the like to an apertured support.

A primary object of the invention is to provide various kinds of fastenersrof the type described wherein the fastener may be mounted onto a support structure by an operation taking place entirely from a readily accessible side thereof. i

A lfurther object of the invention is to provide a fastener that will be easily adjustable in a lateral direction after attachment to an apertured support.

Other objects of the invention will, in part, be obvious, and will, in part, appear hereinafter.

In the drawing:

Fig. 1 is a view of the fastener in perspective;

Fig. 2 is a plan view of the fastener shown in Fig. 1; Fig. 3 is an end view ofthe fastener viewed from the right of Fig. 2; v

jEig. 4 is an elevationof the fastener, partly in secsection, with the molding in place;

Fig. 6 is aplan view of the fastener and plate wherein the fastener is shown in adjusted` position on plate.

AccordingA to the invention, I provide a fastener with tension 12, may be integral, as' inmy preferred embodi-4 ment, with the embossed portion 10I and may extend normally away from a terminal end20 of the embossed tion showing the position of the fastener in the first step in assembly; i

Fig. 5 is an assembly view of the fastener, partly in,

portion 10. Integral with each side edge lpo`rtion722 of the extension 12 is an arm 24 'formed by depressing the side edge 22 and then forming a straight support bear' i ing portion 26 parallel withthe plane of the base por- .Y tion 10, in spaced relation thereto, integralwith the said side edge. 22.VV Fina1ly,'l form Vfrom the support bearing portion 26 -an outwardly and upwardly ,diverging portion 28'wliich is integrally joined at'its outer end to an inwardly and upwardly ,convergingarm portionV 30, The. extension 14 is'similar `in all respects to the extension 12.-

vThe attaching nger-16 projects out of the normal plane of the base 10 in a direction awayfrom the ex tensions 12 and 14 to formfa leg-32. The leg 32 Vis .bent back upon itself to form-an acuteV U-shape hook with theterminal end 34. of. the 'leg 32 formed, to a sup- Vportbiting edge.

4 The attachingnger Y13 projects` out ofthe normalplane ofthe base in adirection away from the extensions 12 relation-with ti1e:leg-32.y The finger 18l is bent back and 14v to form-1a fleg36, in substantially parallelfspaced Patented Apr. 4, 1961 linger 16 is smaller than the chord of the nger 18.

VT0 engage the fastener through the aperture 4t) in a support 42 and against the side faces of the said support adjacent the aperture 40 as shown in Fig. 4 and Fig. 5, the finger 18 is passed through the aperture by a tipping action until its terminal end 38 bears on the support and the leg 36 bears ,against a wall of the aperture. In this position the base [which is of greater area than the aperture 40] rests against the upper side of the support 42 as shown in Fig. 4. An appropriate tool 44 is then placed into the bight 46 of the finger v16 (see Fig. 4) forcing the terminal end 34 to -pass through the aperture at which time the tool 44 is canted against the terminal end 34 in a direction away from finger 1S, causing'it to engage aV portion of the support adjacent to the -aperture as shown -in Fig. 5. A molding 48 can now be engaged with the device as shown in Fig. 5. The device and molding can now be adjusted in a direction parallel to the plane of the fingers 16 and 18 for a distance approximately equal to the diameter of the aperture, minus,

`of course, the space required for the legs.

adjustment of the molding in relation to the supportV 'after the fastener has been applied.

Since certain other obvious modifications may be made in ethis device without departing from the scope of the invention, it is intended that'all matters containedherein be interpreted in an illustrative and not in a limit-V ing sense.

I claim:

A fastening device for use for attaching a molding to a relativelythin support having an aperture therethrough, said fastening device having a base which is provided with means for attachment of said molding at one side of the support and a pair of U-shaped attaching fingers having legs extending from said base through the aperture andy each having an end portion turned outward from said legs and then back toward and engaging the opposite side of the support Vwhen in final position, one of said fingers having a greater distance between its leg and support engaging end portion than the other U-shaped finger and greater than the distance across said aperture,

vthe other U-shapedfinger havingits leg spaced from the leg of said finger less than the distance across said aperture to thereby permitsliding adjustment, the distance between the support engaginglends of said fingers being substantially greater than the distance across said aperture and the support beingsuiiciently thin so that the legs may be passed through .said aperture only by first tipping the said one leg through the aperture and then forcing the said other leg through the aperture while theA fastening device base isA being pressed at against said support.
